The binding sites of Iron atom in the structure of Scapharca Dimeric Hemoglobin, Mutant T72I, Co-Liganded Form (pdb code 5hbi). This binding sites where shown with 5.0 Angstroms radius around Iron atom. The 5hbi structure was solved by W.E.ROYER JUNIOR, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
